As a corollary of these properties, the following important result is proved: for any groupoid, there is a maximal right (left) independent subset.</p>}, journal={Annales Universitatis Paedagogicae Cracoviensis Studia Mathematica}, author={Rezaei, Akbar and Kim, Hee Sik and Saeid, Arsham Borumand}, year={2023}, month={Jul.}, pages={87–98} }
